I am replacing the upper control arm bushings this weekend.  Bus Depot
has them for about $120 for all four.  Easy job if you have a press and
a welder.  If you don't you can easily remove the upper control arm and
take it to a shop for the work.

The uppers get noisy (squeak and groan over bumps, I don't think the
lower control arm or strut bushings wear out, at least mine haven't in
200,000 miles!
